PRECAUTION

PFP:00011

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

AKS004MP

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.

WARNING:

●

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

●

through grounds E13, E26 and E28

●

to combination switch terminal 12

●

through grounds M14 and M78.

LOW SPEED WIPER OPERATION

When the front wiper switch is in LOW position, BCM detects low speed wiper ON signal by BCM wiper switch
reading function.
BCM sent front wiper request signal (LO) with CAN communication line

●

from BCM terminals 39 and 40

●

to IPDM E/R terminals 48 and 49.

When the IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay, located in the IPDM
E/R, power is supplied

●

through IPDM E/R terminal 21 and front wiper high relay and front wiper relay

●

to front wiper motor terminal 3.

Ground is supplied

●

to front wiper motor terminal 1

●

through grounds E13, E26 and E28.

With power and ground is supplied, the front wiper motor operates at low speed.

HI SPEED WIPER OPERATION

When the front wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch
reading function.
BCM sent front wiper request signal (HI) with CAN communication line

●

from BCM terminals 39 and 40

●

to IPDM E/R terminals 48 and 49.

When the IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay and front wiper high
relay located in IPDM E/R, power is supplied

●

through IPDM E/R terminal 31 and front wiper high relay and front wiper relay

●

to front wiper motor terminal 2.

Ground is supplied

●

to front wiper motor terminal 1

●

through grounds E13, E26 and E28.

With power and ground is supplied, the front wiper motor operates at high speed.

INTERMITTENT OPERATION

Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and vehicle speed signal.
After each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

WW-6

FRONT WIPER AND WASHER SYSTEM

Revision: 2005 August

2005 Murano

Wiper Dial Position Setting

Example: For wiper dial position 1
Using combination switch reading function, BCM detects ON/OFF status of intermittent operation dial posi-
tions 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper dial position 1.

●

Intermittent operation dial position 1: ON (Continuity exists between combination switch output 3 and input
1.)

●

Intermittent operation dial position 2: ON (Continuity exists between combination switch output 5 and input
1.)

●

Intermittent operation dial position 3: ON (Continuity exists between combination switch output 4 and input
2.)

BCM determines front wiper intermittent operation delay interval from wiper dial position 1 and vehicle speed,
and sends wiper request signal (INT) to IPDM E/R.

AUTO STOP OPERATION

With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF, power is provided

●

from IPDM E/R terminal 21

●

to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.

When wiper arms reach base of windshield, front wiper motor terminals 1 and 4 are connected, and ground is
supplied

●

to IPDM E/R terminal 32

●

through front wiper motor terminal 4

●

through front wiper motor terminal 1

●

through grounds E13, E26 and E28.

Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When the BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN com-
munication line.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.

WASHER OPERATION

When the wiper switch is in front wiper washer position, BCM detects front wiper washer signal by BCM wiper
switch reading function (Refer to

WW-7, "COMBINATION SWITCH READING FUNCTION"

), combination

switch power is supplied

●

through combination switch terminal 13

●

to front and rear washer motor terminal 1

Ground is supplied

●

to front and rear washer motor terminal 2

●

through combination switch terminal 11

●

to combination switch terminal 12

●

through grounds M14 and M78.

With ground is supplied, front and rear washer motor is operated.

Revision: 2005 August

2005 Murano

When BCM detects that front and rear washer motor has operated for 0.4 seconds or longer, BCM operates
front wiper motor for low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 2 times and stops.

MIST OPERATION

When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops.
For additional information about wiper operation under this condition. Refer to

WW-5, "LOW SPEED WIPER

OPERATION"

If the switch is held in the mist position, low speed operation continues.

FAIL-SAFE FUNCTION

If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is
initiated until ignition switch is turned OFF. (If wipers were operating in LO just before the initiation of fail-safe
status, they continue to operate in LO until ignition switch is turned OFF.)

COMBINATION SWITCH READING FUNCTION
Description

●

BCM reads combination switch (wiper) status, and controls related systems such as head lamps and wip-
ers, according to the results.

●

BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).

Operation Description

●

BCM activates transistors of output terminals (OUTPUT 1-5) periodically and, and allows current to flow in
turn.

●

If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.

●

At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that switch is ON.

BCM - Operation Table of Combination Switches

●

BCM reads operation status of combination switch using combinations shown in table below.

Sample Operation: (When Wiper Switch Turned to LOW Position)

●

When wiper switch is turned to LOW position, front wiper LOW contact in combination switch turns ON. At
this time if OUTPUT 1 transistor is activated, BCM detects that voltage changes in INPUT 3.

●

When BCM detects that voltage changes in INPUT 3 while OUTPUT 1 transistor is ON, it judges that front
wiper switch is in LOW position. Then BCM sends front wiper request signal (LO) to IPDM E/R using CAN
communication.

●

If BCM detects that voltage changes in INPUT 3 when OUTPUT 1 transistor is activated again, it recog-
nizes that wiper switch is still in LOW position.

Revision: 2005 August

2005 Murano

NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.

Operation Mode

Combination switch reading function has operation modes shown below.

Normal status

–

When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.

Sleep status

–

When BCM is in sleep status, transistors of OUTPUT (1 and 5) stop the output, and BCM enters low cur-
rent consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 60 ms, and only input from light switch
system is accepted.

CAN Communication System Description

AKS005MC

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
